IMPROVEMENT IN LUBRICATING--DEVICEFOR SPINDLES.

The Schedule referred to these Letters Patent and making part of the same.

or Apparatus which is Used for Oilingor Lubricating the Spindles of Speeders, Stretcl1ers,'Slubbers, and other roving-frames, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specitcation, in which-v Figure-l is a vertical central section of a Speederspindle, and the principal supporting parts in which the spindle operates, with our invention applied thereto.

Figure 2 is a side elevation, and

Figure 3, a top view of one of our improved lubricators detached.

Our invention consists in the employment of a separate lubricating-device for each spindle of the slubber or other Vroving-frame, said lubricator being an independent as well asa separate device, and has no other function or operation, except to oil or lnb'ricate the spindle.

This invention has for its object to economize (in the use of oil or other lubricant) in time required for applying the lubricating-substance to the spindles, and in the more certain and uniform lubricating-action of the lubricating-material.

In oiling the spindles of slubbers and other roving-v frames, the oil is usually applied to the spindle above the top gear, and is allowed to run down between g and h, g representinglr the hub ofthe top gear, as-seen in fig. 1.

'Surrounds the spindle, and whether the spindle moves up and down in the frame, or the frame moves on the spindle, our oiling-device may be secured to some part ofthe frame, or to the top rail B, and then the spindle may move in and through the oiling-device, or the oiling-device may move. on the spindle with the moving part of thc frame.

This oiling-device consists of a cup or tube, C, having a bottom, D, and a tubular projection, E, which iits the spindle.

An arm, F, is fastened to the side of the cup O, and extends onward or'outward and upward, to connect with some part of the frame, andzhold the oiling-device in its vplace on the spindle.

Within the cup .0, and surrounding the spindle, in contact with its outer surface, is an absorbent, G, which may be felted washers, or sponge, or any fibrous substance that will absorb and properly retain oil and deliver it to the spindle. v

On the top of the absorbent, within the cup, and surrounding the spindle H, we apply a metal or other washer, d, of suicient weight or specific gravity .to

press on the absorbent, and gradually work the. oil out of the latter on .to the spindle, and also prevent the 4absorbent being cariied upward by the downward motion or movement of the spindle when in operation.

In order. to apply our oiling-device, the spindle is raised or drawn upward, the lower end to near the under side of the top rail B, when the oiling-device is slid on to the spindle, and the latter is allowed to move downward to its 'proper position, with the lower end in the step I.-

The oiling-device, is then fastened to some suitable support, and adjusted for the free action of the spindle through the same.

The absorbent is saturated with lubricating-substance, either before or after being applied to the spindle, and if after being applied, such lub1icating.sub stance is applied at and through an annular space, c, between the spindle and the washer d.

After our improvement has been applied to the spindles of a roving-traine, all such spindles are oiled, asl last described, and without stopping the frame.

XVe have found by experiment that, instead of oiling the spindlesof a slubber or a Speeder so frequently, by the use of our improvement such spindles are well and uniformly oiled by filling or charging the absorbent with oil once in about seven days, considerable saving of time is effected, and an immense saving in oil or lubricating-material.

What we claim as our invention, and desire to secure by Letters latent, is

A separate and independent oiling-device with each spindle of a speeder or other roving-frame, when coustrueted and arranged to operate as and for the purpose specified.
